freshwater pump maddening problem
The freshwater pump in our RV (2007 Itasca Navion) stopped holding pressure - it would run up to pressure, stop, then cycle every 15-20 seconds (estimated; never timed on the old pump). Based on advi...

The low point drains on our 2004 Tioga 26Q are hard to access and hard to shut off , if not shut off completely, pump will cycle.
That's not what I meant. I meant if his low point drains have threaded caps instead of valves, use one of those caps on the output connection of the pump. Then turn the pump on to see if the pump holds pressure. This will take all the plumbing out of the equation except the pump. If the pump still cycles when it's capped, the pump is bad. If not, the leak is elsewhere.
I have had to use a garden hose on the low point drain a couple of times to get all of the air out of the inlet side of the pump. The pump sucks on the inlet side where an air bubble remained. Air compresses, water does not. After the pump stops the air pocket under suction seems to pull back through the pump and the pump recycles. And this has happened with brand new pumps.
